SKD18 series IPQAM modulator adopts the compact 1U chassis, which can install 3 independent digital modules. Each module supports 1 Gigabit IP input, 4 arbitrary frequency RF outputs, and hot swapping.  And also supports 12 RF outputs, with DTMB, DVBC (J.83A/B/C), DVBT, and ATSC modulation modes. SKD18 series is high performance and low cost, which is very suitable for using the digital TV headend systems in various business places (such as, hotels, clubs, restaurants, etc.).


Characteristics

1~3 pluggable IPQAM modules, each module has 1 Gigabyte IP input and 4 arbitrary frequency point RF outputs

IP input is available in unicast and multicast protocols, like UDP, IGMP V2/V3

TS stream re-multiplexing function

RF output is available in multi-standard modulation modes, such as, DVBC (J.83A/B/C), DVBT, DTMB, ATSC

RF output is agile, the frequency can be adjusted freely between 50-1000MHz
